- Step 3: Add ground beef to the skillet, cooking until fully browned while breaking it apart as it cooks.

Tips & Variations
- For extra flavor, try adding a splash of beef broth to the skillet during simmering to keep the mixture moist and rich.
- Substitute Swiss cheese with Gruyère for a nuttier, more authentic French onion flavor.
- Use whole wheat or brioche buns to add a different texture and depth of taste.
Storage
Store leftover beef mixture in an airtight container in the refrigerator for up to 3 days. Reheat gently on the stovetop or in the microwave until warmed through. Assemble sandwiches fresh to keep buns from becoming soggy.

FAQs
Can I use ground turkey instead of beef?
Yes, ground turkey is a leaner alternative and can be used in the same way. Just be mindful it may cook faster and can dry out, so watch the simmer time.
How can I make this dish vegetarian?
Substitute the ground beef with cooked lentils or a plant-based meat alternative and use vegetable broth instead of Worcestershire sauce (as it often contains anchovies). The caramelized onions and spices will still deliver great flavor.

Ingredients
Beef Mixture
- 1 pound ground beef
- 1 large onion, sliced
- 2 cloves garlic, minced
- 1 tablespoon olive oil
- 1 teaspoon Worcestershire sauce
- 1 teaspoon soy sauce
- 1 teaspoon dried thyme
- Salt and pepper to taste
Assembly
- 4 chicken hamburger buns
- 1 cup shredded Swiss cheese
Instructions
- Caramelize Onions: In a skillet, heat olive oil over medium heat. Add sliced onions and cook, stirring occasionally, for 10-12 minutes until they become golden brown and caramelized, bringing out their natural sweetness.
- Add Garlic: Stir in minced garlic and cook for an additional 1-2 minutes until fragrant, being careful not to burn the garlic.
- Cook Ground Beef: Add the ground beef to the skillet with the onions and garlic. Cook thoroughly, breaking the meat apart with a spoon or spatula, until fully browned and no longer pink.
- Season Beef Mixture: Drain any excess fat from the skillet. Stir in Worcestershire sauce, soy sauce, dried thyme, salt, and pepper. Reduce heat and let the mixture simmer gently for 5 minutes, allowing flavors to meld.
- Toast Buns: Toast the chicken hamburger buns until golden brown to add a slight crunch and prevent sogginess when assembled.
- Assemble Sloppy Joes: Spoon the beef and onion mixture generously onto the bottom half of each toasted bun. Top with shredded Swiss cheese while the filling is hot, allowing it to melt slightly, then place the top bun on each sandwich.
Notes
- For deeper flavor, use caramelized onions that are cooked slowly on low heat.
- Substitute Swiss cheese with Gruyere or mozzarella if preferred.
- Serve with pickles or a side salad for a complete meal.
- Using chicken hamburger buns adds a lighter twist, but regular beef buns or brioche buns also work well.
- Adjust seasoning to taste, especially salt, depending on soy sauce and Worcestershire sauce brands.
